BARREL.

SPECIFICATION forming part of Letters Patent No. 537,592, dated April16, 1895. Application filed February 1,1892. Serial No. 419,979. (Nomodel.)

To all whom, it may concern:

Be it known Ithat I, CARL WITTKowsKY, a subject of the King of Prussia,German Emperor, and a resident of Berlin, in the Kingdom of Prussia,German Empire, have invented certain new and useful Improvements.

e In carrying my improved method into practice, I Iirst produce athree-ply veneer-board by uniting three plates of veneer by means of awatertight glue, and in a dat state. The arrangement of the three plateswith regard to their grains is such a one, that the grainV of themiddle-or centralveneer is run perpendicularly to the longitudinal axisof the barrel to be produced, while the grains of the two outer platesof veneer are running rectangularly to the grains of the said innerveneer, or parallel to the longitudinal axis of the barrel to beproduced.

The three plates of veneer united by the waterproof glue are kept intheir dat position until the glue has become perfectly dry. Thereafter,the three-ply veneer-board is bent into the proper shape so as to form acylinder. Before, however, bending the veneer-board, I cut those twoedges, by means of which the cylinder is afterward closed, obliquely;and after having bent the board, I unite the said two oblique edges bymeans of the'same waterproof glue. The line of junction is at the outerside of the barrel covered by a strip of tion through the same.

In said figures a is the middle-or inner veneer, the grains of which arerun around the barrel, or reetangularly to the longitudinal axis of thesame. a and a2 are the two other veneers, one of which (a2) lies at 'theoutside of the mantel, While the other one (a) lies at the inside of thesame. The grains of these two plates are crossing those of the third,t'. e., the inner one.

The breadth of the plates of veneer (with regard to the lengthof thebarrel) is different, in that the outer veneer a2 is broader than thetwoother ones, so that at each frontal side of the barrel, a part of theouter veneer projects over the two other ones. The edges of these latterare forming the seat for the bottoms b b', as'distinctly to be seen inFig. 2, and the bottoms after being placed upon the said seats aresecured in place by a suitable strip c, or c respectively, of veneerglued with its outer surface to the inner surface ofthe projecting endof the outer veneer a2.

It will be seen, that the bottoms shown in Fig. 2 are consisting eachalso of two crossed plates of veneer. This, however, does not form apart of my invention.

d, Fig. l, is a strip of veneer covering the outer line of junction'between the two inclined surfaces of junction e, (Fig. 1,) and it willbe seen, that by-broadening the said surfaces the junction becomes byfar a better one.

Having thus fully described the nature of this invention, what I desireto secure by Letters Patent of the United States is- The method ofmanufacturing wooden barrels, consisting in uniting by means ofwaterproof glue three plates ofveneer'in a Hat state, letting said gluebecome dry, bending then the three-fold veneer board, and uniting theopposite edges by waterproof glue, the line of junction being'covered bya strip of veneer also iixed by waterproof glue, and inserting finallythe bottoms, substantially as described.

In testimony whereof I have signed this specification in the presence oftwo subscribing witnesses.
